A lot of architectures allow multiple audit_arches at runtime due to compat support and
similar features, so it really does want to be a function. The goal of this patch set is
to get it supported everywhere.
I was wondering if we could have a common syscall_get_arch() simply returning an
per-arch AUDIT_ARCH. But seems like the function itself needs to be per arch
anyways due to the nuances above.
